I've been using epoc switch for 1.2 and 2.0 sdk. Everything was fine.
I installed 2.1 and 2 FP2, and sdk for nokia communicator and whenever I try to use sdk 1.2 or 2.1, or any sdk, I cannot run my apps, although it compile. Whenever I try to run my apps in the emulator, it says System Error! I even tried to run the simple test application from application wizard, and it still says system error!
Is it becoz of the multiple sdks?
